The thin-path wet cell is designed for both morphological and chemical characterization of up to 100 μL of sample. It is ideal for applications such as the identification of subvisible particles in therapeutics (described by guidance in USP <787> and USP <788>), especially when a traditional membrane filtering approach may risk changing particles of interest, such as protein aggregates. Includes 1 pair of fused silica glass windows (MOR4551), 10 spacers, 2 glass positioning tools, 5 1mL syringes and a holder/draining rack for the glass disks (requires Morphologi software version 8.20 and higher)
